Short for Connected Limited Device Configuration. CLDC is the J2ME configuration for smaller handheld devices that are usually battery operated and low in memory with limited processing power and low bandwidth.
Most often the CLDC uses the K virtual machine, which is suitable for devices with 16/32-bit RISC/CISC microprocessors/controllers, and with as little as 160 K of total memory available -- 128 K of which is for the storage of the actual virtual machine and libraries themselves.
CLDC reference implementation and KVM runs on Windows 98/NT, Solaris, and Palm platforms. Developers can access binary releases of the CLDC, or they can get the full release by signing legal forms from Sun.
